About this lesson: This engaging CAD and robotics lesson introduces students to the world of Computer-Aided Design (CAD) using Tinkercad to create a simple mechanical toy - a pinwheel.
While designing and simulating their toy, students explore foundational STEM and engineering concepts such as pivots, linkages, and alignment. The lesson encourages critical thinking and creativity as students consider how design choices impact toy safety, durability, and social value - especially for children in under-resourced communities. Through hands-on 3D modelling, simulation testing, and structured reflection, learners develop essential design skills and gain exposure to real-world applications of robotics and coding.
